Fig. 4 is an endview at the cylinder ends in larger size and with the plate removed toexpose the chambers. Fig. 5 is a face view of the valve mechanism inlarger size, showing also the connecticnsforsupply of gas when such isdesired. Fig. 6 is au end view of the main cylinder with the headremoved. Fig. 7 shows the main valves. Fig. Sis a detail of the gas-supy3o ply devices, which l reserve the right to claim in a separateapplication. Fig. 9 is a detail view ofthe mechanism for operating theairsupply valves, and Figs. 10, 11, and 12 are detail views ofthegovernor. Fig. 13 shows the main slide-valve.

A is the bed-plate, of suitable character, supporting a crankshaft,a onpillow-blocks b` b.

B is the main cylinder, provided with pistou c and rod d, connected to across-head, e,

4o that is fitted on slidewaysf. gis a rod connecting from slide c tothe crank-shaft a.

C is the cylinder of the air-pump on the bedplate A, below the maincylinder B, provided with piston h and a rod, i, that connects to aslide, 7c l, a'rock-leverpivoted on the bed-plate, and connecting by arod, m, to slide lc, ainlalsoA by a rod, n, to a crank-disk on asecondary shaft, p,sustained o n pillow-blocks b, on which is awheel, o,gearing with a larger Wheel, q,

5o on` the main crank-shaft a, whereby thefshat't p is caused to maketwo revolutions to one of the main shaft. The rod n connects to thecrank-pin of rock-lever Z by an open hook, which allows its readydisconnection, and the lever has an aperture to receive a hand-bar foruse to operate the air-pump by hand in' starting the engine.

The pump-cylinder C is formed at itsends with compression-chambers rr,communicat ing with the interior of the cylinder by openings that arefitted with dish-valvess, closed by springs. Inlet-pipes t, withsuitable valves, are also fitted in connection with the cylinder.

Above the compression-chambers r are generating-chambers u u,communicating therewith by openings, above which are raisedvalve seatsc, having side openiu gs. Upon the valveseats 'o are slide-valves w,attached to plates on the ends of rods i, that pass through the heads ofchambers u, above which the rods are connectedto the ends of rock-leversa. A shaft, b, sustained in suitable bearings at the side of cylinder B,carries cams c c', that act on rods d d from the ends of levers a',whereby the valves 'w are moved down to close the outlets in valve-faces@,the return movement being given by spiral springs on rods d. (Seedetail, Fig. 9.) 'lhe shaft b extends to the secondary shaft p, where itcarries a bevel-pinion, e', that engages a similar pinion on shaft p, sothat the shaft b is rotated and the valves n1 opened in proper time andorder.

f', provided with plungers g', which, as shown most clearly in Fig. 5,are suspended from elneous movement by a rod, i.' Une lever li isconnected by a rod, 7c', to the strap of an eccentric, l, on main shafta, for operation of p lungers g. Service-pipes m from a suitable and inthe pipes nz are regulating-valves n. From the pumps pipes o pass to thegenerating-chambers n. lThe main valve-chambers are at pp, on one sideof the main cylinder B, and communicate directly with thegenerating-cham bers u. q, -Figs.1 and 5, are the ports from the chamberp to cylinder B, and r are the exhaustv ports of the chamber.

The slidefvalves s (shown separately in Figs. 7 and 13) are connected bya valve-rod, t', which Above the chambers r are water-pumpsf source ofwater-supply connect to pumps f',

SoV

bow-levers h', that are connected for simulta- Ico is operated by aconnecting-rod, u', from an eccentric, e', on main shaft a. Fig. 13shows the packings of the slide-valve, which consist of plates S4,pressed to the valve by springs S5, that-are behind Athe plates in holesformed in the cover and one end of the chest, set-screws Ss beingprovided to regulate the tension of the springs.

The construction so far as described p'rovides for supply of air andwater to the generating-chambers. Forheating and expanding the air andconverting the water to steam I use an electric arc in thegenerating-chamber, as next described.

a2 a2, Figs. 4 and 5, are tubes of non-conducting material extendingthrough the sides ofthe generating-chambers, and fitted with carbons b2,that are-to be connected outside the chambers with a battery ordynamo-electric machine of suitable power.

c2 are perforated plates in the chambers above the carbon points andbelow the watersupply pipes o', so as to receive the water and act asscreens and finely divide it. Suitable feeding and regulating devicesare provided in connection with the carbons.

I also provide for regulating the ow of water to the generating-chamberby automatic governing mechanism shown in Figs. 1, 2, and 10, andconsisting as follows:

E is a governor of the centrifugal type, 'xed on cylinder B, of which d2is the sliding stem, moved by the arms and balls.

l2 is a valve-stem supported at its ends in valve-chambers f2, andprovided with an arm, g2, to which the stem ol2 is connected. Thevalve-chambers f2 are placed between the pumps f and the ends ofservice-pipes m', (see Figs. l and 11,) so that the water going to thepumps shall pass through the chambers, and the ends of stem l2 cover theinlet ot' the service-pipes to the chamber. The stem is hollowed ont andslotted at h2 to register with the inlets to the chamber, so that theinlet shall be increased and decreased by the rocking motion ot' thevalve-stem given toit by the governor E.

For regulating the amount of air pumped at each stroke of the air-pump,and consequently regulating the pressure in chamber, .l provide forVarying the stroke of the pumppiston It by means ot' a hand-wheel andscrew, i2, on the rock-lever l, connected to a slide on the lever thatcarries the wrist-pin of the rod n.

' The operation is as follows: To start the engine, rod it is to beunhooked and the rock-lever l worked by a hand-bar to operate the .pumpC and force air into the compressionchambers 'r and. generators u. Theelectric current is next put onto the ca rbons, and, the arc beingformed, the compressed air is heated, after which rod u is lo beconnected for work. The rod lc is then to be unhooked from the'pump-levers h', so that the pumps f can be worked by hand.Service-valves u' are to be opened, thereby allowing water to pass toval vechambers f2, and the pumps being operated, the water goes by pipeso to the generatingchambersu, and, dropping upon the perforated platesc2, is instantlyconverted to steam. Rod lo is then replaced and rod u oftheslide-valves disconnected, and the engine is ready to start in eitherdirection as the valve-rod t may be moved. Any desired pressure may begot before starting the engine, and the water may be heated before beingpassed to the pumps by using exhaust-steam in any suitable manner. Theair-pump makes two lull strokes to every one ot' the main-piston. Theoutlet-valvess of the air-pump close and the valves w open before thestroke ot' the main piston is completed, and the water is injected intothe generator at the same moment, so that there is time for the expansinof the air and conversion of the water to steam before the main valve sopens, the operation being the same at each end.

In place of supplying jets of water to the generator, or in yconnectionwith the water, explosive gases, gasoline, or crude petroleum may beinjected.

For supplying gasoline or other explosive liquid I connect thesupply-pipes to the service-valves n and the liquid passed in with thewater for conversion to gas by the electric heat.

To supply gas I connect a pipe from a gasometer to cocks L31?, that areattached to the sides ofthe generating-chambers, (see Fig.5,) and fromthe cocks Z3 exible tubes m2 pass to service-valves n. Acompression-bar,u2, Figs. 5 and 8, connected to the rod t of the main valves, so as tomove with the valves, extends to the flexible tubes m2 and. acts tocompress them alternately against the fixed lugs o2, and

thus cut oft the supply of gas to the servicevalves a. In the ends ot'bar n2 are fitted blocks p2, ot' hard rubber, -projected by spiralsprings q2, the object being to retain the ilexible tubes compressedafter the bar starts back.

r2 is the stem of the two gas-cocks Z3, provided with an arm, s2, thatis connected by a link, t2, with the arm g2 of the governing valvesteml2, so that the governor E shall regulate the gas and the water supplysimultaneously.

By this construction I combine for the operation of the engine theforces of compressed and heated air, steam, and explosive gases,electricity being the converting force that brings the combined forcesinto action.

I may dispense with either water or gas in the combination, as foundmost convenient, and the air, water, and gases are to be supplied in anysuitable proportions.

It will be understood that I reserve the right to claim in a separateapplication the devices for feeding or supplying gases to the engine.

Having thusfully described myinvention, I claim as new and desire tosecure by Letters Patentl. In engines, the combinationof a pump forsupplying water in jets and a pump for supplying compressed air with agenerating- IOO IIO
